Why This Sirloin Tip Roast Recipe Works for Keto

When it comes to the keto diet, the goal is to keep your carb intake low and your fat intake high, and this Herb-Crusted Sirloin Tip Roast fits the bill perfectly. The main ingredient, sirloin tip, is a lean cut of beef that’s high in protein and virtually carb-free. The high-fat content comes from the olive oil and the natural fats within the meat, which help to keep you feeling full and satisfied.

The herbs and spices used in the crust not only add incredible flavor but also provide health benefits. Rosemary and thyme, for instance, are known for their anti-inflammatory properties and can aid in digestion, which is great for those on a ketogenic diet. Additionally, they contain minimal carbs, making them ideal for adding depth to your dishes without compromising your carb count.

Another key ingredient in this recipe is garlic, which not only enhances the taste but also has been shown to have numerous health benefits, including improved heart health and immune function. The combination of these ingredients creates a dish that is not only delicious but also packed with nutrients that support a healthy keto lifestyle.

Preparing Sirloin Tip Roast

Mastering the Method for a Perfect Roast

Creating the perfect herb-crusted sirloin tip roast is all about technique. To start, you’ll want to preheat your oven to the right temperature to ensure even cooking. When preparing your herb crust, it’s important to finely chop the fresh herbs for maximum flavor release and to ensure they adhere well to the meat.

Before applying the herb mixture, make sure to pat the roast dry with paper towels. This step is crucial for helping the herbs and seasonings stick to the meat. When rubbing the olive oil and herb mixture onto the roast, do so evenly and thoroughly to cover the entire surface.

While the roast is in the oven, keep an eye on the meat thermometer to achieve your desired level of doneness. Remember, letting the meat rest after cooking is not just a suggestion—it’s a must for a juicy, flavorful roast. This allows the juices to redistribute, ensuring that every slice is as succulent as the last.

Variations to Spice Up Your Sirloin Tip Roast

Spicy Sirloin Tip Roast

For those who love a bit of heat, consider adding crushed red pepper flakes or cayenne pepper to the herb crust mixture. This will give your roast a spicy kick that complements the savory herbs beautifully.

Garlic Butter Sirloin Tip Roast

Enhance the richness of your roast by creating a garlic butter mixture to apply to the meat after cooking. Simply mix softened butter with minced garlic and herbs, then spread over the warm roast before serving.

Citrus-Herb Sirloin Tip Roast

Adding a zesty twist to your roast is easy with the addition of citrus. Grate some lemon or orange zest into your herb mixture for a refreshing and tangy flavor that brightens up the dish.

Substitutions for Your Dietary Needs

While this recipe is already keto-friendly, there may be times when you need to make substitutions to cater to other dietary restrictions or preferences. Here are a few options:

Herb Substitutions: If you don’t have fresh herbs on hand, dried herbs can be used in a pinch. Just remember that dried herbs are more potent, so you’ll want to use about one-third of the amount called for fresh.

Oil Substitutions: If you prefer not to use olive oil, other high-fat, keto-friendly oils like avocado oil or melted ghee can be great alternatives.

Spice Substitutions: If you’re not a fan of mustard powder or paprika, feel free to omit them or swap them out for other spices you enjoy. Just be sure to keep an eye on the carb content if you’re strict about your keto macros.

  • Roasting pan
  • Meat thermometer
  • Cutting board
  • Chef’s knife
  • Small mixing bowl
  • Measuring spoons


  • 3 lbs sirloin tip roast
  • 2 tbsp olive oil
  • 2 tbsp fresh rosemary finely chopped
  • 2 tbsp fresh thyme finely chopped
  • 4 cloves garlic minced
  • 1 tbsp sea salt
  • 1 tsp black pepper freshly ground
  • 1 tsp mustard powder
  • ½ tsp onion powder
  • ½ tsp paprika


  • Preheat your oven to 375°F (190°C). Place the oven rack in the middle position.
  • In a small bowl, combine the chopped rosemary, thyme, minced garlic, sea salt, black pepper, mustard powder, onion powder, and paprika to create the herb crust mixture.
  • Pat the sirloin tip roast dry with paper towels. This will help the herbs and seasonings adhere better to the meat.
  • Rub the olive oil over the entire surface of the roast. Then, evenly coat the roast with the herb mixture, pressing gently to make sure it sticks.
  • Place the herb-coated roast on a rack in a roasting pan. Insert a meat thermometer into the thickest part of the roast.
  • Roast in the preheated oven for approximately 1 hour and 30 minutes, or until the meat thermometer reads 135°F (57°C) for medium-rare.
  • Remove the roast from the oven and let it rest for 15-20 minutes before slicing. This allows the juices to redistribute throughout the meat, ensuring a moist and flavorful roast.
  • Slice against the grain and serve.


Letting the roast sit at room temperature for about 30 minutes before cooking can help ensure more even cooking. For those who prefer their meat more or less done, adjust the final internal temperature to your liking (145°F for medium, 160°F for medium-well). Leftover roast can be sliced thinly for a delicious keto-friendly sandwich alternative or salad topping.
